无论我们使用哪个主机商,都需要注意的数据安全备份。我们可以每月备份一次,或者每周备份一次,或者每天备份。且我们可以备份的形式有很多种,比如我们可以每天手动备份、服务器环境自带的第三方对象存储备份,或者备份到邮箱中。甚至我们可以用这里通用的脚本备份。
毕竟不是所有的WEB环境都有自动备份的软件支持。这里我们可以用这个备份脚本 backup.sh 实现快速备份。

我们可以将脚本保存到backup.sh文件,然后需要先修改配置。
这个备份脚本是可以将文件备份到我们第三方FTP空间的。
修改文笔之后,我们保存。
30 3 * * * sh ~/tools/backup.sh
我们可以设置定时备份运行。可以先运行一次看看是否备份成功。
